The exam
DVA-C03 validates a candidate's proficiency in developing, testing, deploying, and debugging AWS Cloud-based applications — writing code for AWS services and Lambda, using data stores in application development, implementing authentication/authorization and encryption, packaging and deploying via CI/CD workflows, and troubleshooting and optimizing application code in production.
Who it is for
The target candidate has 1 or more years of hands-on experience developing and maintaining applications by using AWS services, with proficiency in at least one high-level programming language, understanding of application lifecycle management, and experience using development tools. Candidates develop and secure applications by using AWS service APIs, the AWS CLI, and SDKs, and use a CI/CD pipeline to deploy applications on AWS. Designing architectures, designing CI/CD pipelines from scratch, administering IAM users/groups, administering servers, and designing networking infrastructure are explicitly out of scope for this role.

What Preppio gives you
Across every domain above, in 5 formats: concept, scenario, ordering, multi-select, matching. Each one explains why the right answer is right and every distractor wrong.
Per domain, whether you are ready, weak, or not started — the same domains and weights as the exam itself.

Sample 1 · Concept
A developer is using Amazon Q Developer inside an IDE to help refactor a Python Lambda function that processes Amazon S3 event notifications. The developer wants Amazon Q Developer to generate an inline code suggestion for parsing the S3 event structure without leaving the editor or manually invoking a separate chat interface. Which capability of Amazon Q Developer directly supports this workflow?

4 domains, weighted as the exam weights them: Development with AWS Services (30%), Security (26%), Testing and Deployment (22%) and Troubleshooting and Optimization (22%). Your readiness map in the app is organised by the same domains, so what you study against is what the exam tests.
Five formats: concept, scenario, ordering, multi-select and matching. The practice questions use every one of them, and the sample on this page shows one of each.
DVA-C03 is on the Single, Dual and All Access plans. You start on the free tier and add it from the plan picker inside the app. Three fundamentals exams (AZ-900, CLF-C02 and CDL) are always free, and the sample on this page is free to try.
Every question is generated from the exam's published objectives, then checked for accuracy, answer key and explanation before it is served. Nothing is copied from any exam, questions rotate by how often they have been seen, and they are retired when the objectives change.
